PHP复制并重命名文件

Question

I have a file I'm attempting to move and Im able to do so, however I can't seem to change the filename exactly how I need it.

$file1 = "/../../../../../../rooms.GENRE.FILENAME/FILENAMEentry.html";
$newfile1 = "/../../../../creative/$path/ $dir entry.html";
copy($file1, $newfile1);

$dir is the variable with the name of the file I'm calling. this returns the file name as FILENAME entry.html and I need the space between them removed.

I've tried it without the space as in

$direntry.html and that moves and creates the file but just names it .html

Basically I'm replacing where it says FILENAMEentry.html (the capitalized portion) with the name of the filename in $dir

Answer 1

考虑使用串联：

$newfile1 = "/../../../../creative/$path/" . $dir . 'entry.html';

Answer 2

Actually $dir works while echoing but you have space and if you write them together the word would be $direntry which will be ambiguous for the interpreter so use concatenation. change

$newfile1 = "/../../../../creative/$path/ $dir entry.html";

to

$newfile1 = "/../../../../creative/$path/".$dir."entry.html";

Answer 3

You should check out these string operators .

This should work fine:

$file1 = "/../../../../../../rooms.GENRE.FILENAME/FILENAMEentry.html";
$newfile1 = "/../../../../creative/$path/".$dir."entry.html";

if (!copy($file1, $newfile1)) {
    echo "failed to copy file.";
}

 <?php "{$str1}{$str2}{$str3}"; // one concat = fast $str1. $str2. $str3; // two concats = slow ?> 

Use double quotes to concat more than two strings instead of multiple '.' operators. PHP is forced to re-concatenate with every '.' operator.

$newfile1 = "/../../../../creative/$path/{$dir}entry.html";
